To all whom it may concern.-

Be it known that 1, JOHN ALLEN HEANY, a citizen of the United States, residin at York, in the county of York and State 0 Pennsyl vania, have invented certain new and useful Improvements in Machines for Ap lying Coverings to Wire, of which the foliowing is a specification.

My invention has relation to a machine for applying'a covering, such as flocculent asbestos, to a rotating and traveling wire and for compacting and coating the covered wire with a waterproof material and thereafter drying the covering and coatin upon the wire, and in such connection itre ates to the construction and arrangement of such a machine.

- In United States Letters Patent No.

740,131, granted to me on September 29,

1903 there is described and claimed a method of producing insulated electric conductors. Among the steps therein enumerated are those in which a rotating and traveling wire is coated with a gluey material, then covered with-flocculent asbestos, then the covering compacted, and finally the covered wlre coat ed with an indestructible paste or cement. In this present application for a patent the mechanism and means for coating the wire with the gluey material, compacting the covering upon the wire, coating the covered wire with the paste or cement, and drying the coated covered wire forms the subject-matter of the invention.

The nature vand scope of my invention will 3 be. more fully understood from thefollowing description, taken in connection WIth the accompanying drawings, forming part hereof, in which- Figure 1 is a top or plan view of a machine embodying main features of my invention, certain of the parts being'broken awa Fig. 2 is a side elevational view thereof. Fig. 3 1s a cross-sectional view taken on the line 3 3 of Fig. 1, illustrating the construction and arrangementof one o the divided dies for compacting the covering on the wire. Fi 4 is a top or plan view, partly sectioned, il ustrating the construction and arran ement of the vat containing the paste and t e means for applying the paste to the covered wire and for compacting the covering upon the wire. Fig. 5 1s a 'longitudina sectional view of Fig. 4. Fig. 6 is a still further enlar ed cross-sectional view illustrating in detai one of the compacting-dies, and Fig. 7 is an enlarged cross-sectional view illustrating the means for drying the covered wire after the coating has been applied.

Referring to the drawings, the wire a, after a rotary and forward movement has been given to it, as described in a companion application for a patent filed .by me on January 20, 1904, under Serial N 0. 189,804, traverses a vat 1), containing a gluey material. This vat b is of an ordinary glue-pot construction and has rotating partly through the gluey mass 3. grooved wheel over which the Wire (1 passes to take up from the wheel sufficient glue to coat the Wire. The wire a then passes through a funnel-shaped tube in the vat b, in order that surplus gluey material may be removed from the wire a and returned to the vat.. The water-bath in which the vat b is held may be heated by a jet 6.

The preferred construction and internal arrangement of vat b are the same as in the vat f illustrated in detail in Fi s. 4 and 5. I

After being coated wit glue, as aforesaid, the wire a next passes adjacent to a mechanism B for supplying the flocculent material spirally to the wire. This mechanism is described and illustrated in a com pani'on application for a patent filed by me under date of January 20, 1904, and Serial No. 189,805. One of the main elements of this mechanism is the band B of card-clothing, which travels obliquely to the direction of travel of wire a, as Illustrated in Figs. 1 and 2. After receiving its covering the wire next asses through one or more compactingdies Each of these dies consists of two members, the lower (1 being a stationary bar which is supported by the framework or of the machine, while the other member d consists of a die or arm pivoted at one end to a shaft (i supported by framework 0,, and its other end is adapted to be engaged by means for locking the membe: down upon the mem'- ber (1 under s ringtension. A preferred construction 0 divided compacting-die is illustrated in d tail in Fig. 6. It consists of a die-bar d comprisin the fixed member having notches d, whic separate the grooved die-surfaces d" from each other, and an arm (1, having a groove registering with a comd is pivoted at one end on the shaft d, and the other end is slotted, as at d, to receive a bolt (1, projecting from an oscillatory shaft the die throng or pind". T he bolt (i has on its upper screwthreaded end an adjustable thumb nut (l and coiled round the body of the bolt (1 is a spiral spring d, one end of which bears against the adjustable thumb-nut d, and the other end bears upon or carries a collar d loosely sliding upon the bolt (P. A set-nut d is adjusted upon the bolt (i below the collar d. When the die-arm d is thrown over, so that its groove registers with the groove in one of the die-surfaces d of the bar 1, the bolt al is swung or locked in the slot of thediearm (1 so that the collar d presses upon the die-arm d with more or less spring-pressure, regulated by the thumb-nut d. The setnut (1 serves to limit the downward movement of the die-arm (1 when the same is engaged by the bolt (i The movable collar d is adapted to press upon the die-arm (Z and to permit uneven surfaces of the covering of the Wire a to pass under the die-arm d and at the same time furnish the necessary pressure by the intervention of the spring (1 to compact or compress the covering upon the wire (1, The s ace bet the members of h which the co must pass may thus be regulated By using a plurality of dies d, each regula separately, the flocculent covering on the wire a is compacted more and more by successive dies until the necessary degree of compactness of the covering by the gradual increasing pressure exerted on the same by the diesd is obtained. If desired, any one or more of the die-arms 11 in series, may be thrown out of action, asrequired, by lifting up out of engagement one or more of the die-bars d, as illustrated, for example, inFig. 4. After the covering on the wire a has been applied and compacted, as explained, the covered Wire a? next traverses a vat f, containing a paste or cement of fireproof materials. This vat f is a duplicate of the glue-vat b. The covered wire 0, receives its coating of paste or cement from the wheelf rotating through paste 4 in the vat, and surplus paste is scraped from the wire a by the funnel-shaped tube f through which the wire a next passes.

The wire a, covered and coated, is then drawn through a second series of dies (1, constructed and arranged as hereinbefore described. The coating and covering of the wire a is thus compacted, and the wire next passes to the drying mechanism. Thjs mechanism consists, essentially, of an arched I which the wire a? travels.

frame g, having at its top a groove g, along One or more gasjets 9 located in the frame 9 below the top, sup ly the necessary heat. The frame g is pre erably pivoted at one end, as at 9 in a stationary part of the machine, and the other end is provided with a handle 9 by means of which the frame may be raised from or lowered toward the jets g. The handle 9 has for this purpose a cam projection 9 bearing upon a fixed part of the machine, so that being swung around, as indicated in dotted lines in Fig. 7, the frame 9 may be lowered.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is

1 In a machine of the character described, in combination with means for supplying glue to a rotating and traveling wire and means for supplying a covering of fiocculent material thereafter to said wire, a die-bar and movable dies engaging said die-bar, said diebar and movable dies being arranged to compact with a gradually-increasing pressure the covering upon said wire.
